Crisp Delf Mine is a sandstone mine near Skelmersdale, and one of the finest underground structures I've visited for a long while. The caverns are enormous, my photos just don't do it justice and go on for what seem like hundreds of yards into other caverns. There's even an underground stream with cold clear pools.
Each "JENGA block" in my photos (they are actually concrete sleepers) is at least a foot thick, so that should give you some scale.
